SILENT FRICTION GRIP SASH CONTROL Filed July 25, 1928 4 Sheets-Sheet 4 Patented Feb. 11, 1930 GEORGE E. SRACK, F TULSA, OKLAHOMA SILENT FRICTION-GRIP SASH CONTROL Application filed. July 23,

My invention relates to friction latches for windows of buildings of residences and buildings for business purposes, also for car windows, automobile windows, and aeroplanes,

and sea going vessels; and the object isto provide windows generally with controlling means for preventing rattling and for preventing the binding of the window sash in the vertical channels. One object is to provide means for holding windows in any desired position and which will prevent rattling of the windows and which will make the windows easily operated and which will also be provided with automatic locking means for checking burglars or preventing burglars from opening Windows. Other objects and advantages willbe fully explained in the following description and the invention will be more particularly pointed out in the claims.

Similar characters of reference are used to indicate the same parts throughout the several views.

The drawings show parts 1 and 2 of a window frame and a sash mounted therein which is provided withuprights 3 and 41, as frame members. Bearing members are provided and consist of uprights 5 formed of sheet metal andbeveled and attached to the window frame members 1 and 2 and serve somewhat as stops. The gripping members 6 are mounted between the sash members 3 and 4 and the bearing members 5. The bearing members 5 have inclined surfaces and the gripping members 6 have inclined surfaces and the gripping members 6 are pressed into the acute angles formed by the bearing members 5. This places the gripping members in osition to hold the sash at any required eight by friction. The sash frames 3 and 4 are provided with bearing members which consist of metallic strips bent to angular form and attached to the sash frames 3 and 4, the part 7 is attached to the face of the sash while the member 8 extends on the edge of the sash.

The gripping members 6 are hingedly connected to the upper ends of the sash frame. The sash frame is morticed out to make space for springs 11. The gripping members 6 are provided with lugs 15 rigid therewith. These lugs 15 pass through the eyes 14 of the springs 11 and the bearing members 7 have elongated openings 16 to provide working space for the lugs 15. Bearing sockets 23 are struck from the bearing members 8 and bent to provide supports for the springs 11 and lugs 12 are also struck from the bearing members 8 to support the bottom ends of the springs 11. In making the elongated openings 16, the metal out therefrom is not severed but is bent to form the lugs 24 and these lugs form back stops for the springs 11. The gripping members 6 are thus provided with hinged. connections at their upper ends and these connections are made resilient and yielding to permit automatic adjustment of the upper ends of the gripping members 6. This adjustment of the upper ends of the gripping members 6 is to make it possible for the adjustment of the gripping members at their bottom ends, Without this automatic adjustment at their upper ends, the swinging ends or bottom ends of the gripping members 6 would not always perform their functions of gripping the sash and the bearing members together, because gripping members 6 would not be pressed far enough in between the bearing members 5 and the sash members 3 and 4 at their lower ends. Springs 9 are provided for pressing the gripping members 6 into their gripping positions. The springs 9 are attached to the bearing members 8 by lugs and 28 which are struck from bearing members 8. The springs 9 engage the lugs 22 for pressing the gripping members 6 into gripping position. The lugs 22 are integral a with the gripping members 6. The gripping members 6 are provided with friction surfaces 17.

The window sash may be automatically locked by lugs 39 entering the slots 27in gripping mernbers 6. The sash is provided with sash lifters 19 and the gripping members 6 are provided with extensions 18 for guiding the gripping members 6 in the operations of the gripping members in passing to and from the gripping positions and lugs 20 on the lifting brackets serve as guides for the tensions 18. The extensions 18 are provided with ribs or beads 26 for strengthening purposes. Beads or ribs are provided on the upper ends of the gripping members 6 for strengthening purposes. The extensions 18 are provided with bearings for the finger of the operator and corresponding bearing members 19 on the sash lifters 19 for the thumb of the operator in manipulating the gripping members 6.

The variation in Fig. 9 consists of an ex tension 30 to serve as a parting bead and sliding surface of the second sash.

The variation shown in Fig. 10 is provided for coach work or sash for coaches. This structure is provided with extensions 31 and 32 for regulating the shade channel 33.

The variation shown in Fig. 11 consists of extensions 34 and 35 for use in light weight sash in automobiles. The devices shown in Fig. 12 are similar to Fig. 8 and are provided with a shift key 36 with diagonal slots 37. This form is provided with an elongated opening 38 to permit shifting of the bearing member.

The spring 9 is provided with a shoulder 29 which engages the offset of bearing member 8 adjacent to the lug 28.

Figs. 15 to 21 inclusive show slight variations in the bearing and gripping members. The socket member 41 is provided with a bearing 52 for lug 45. The gripping member has a throat and a shoulder 46 for supporting and housing the spring 42. A folding member 51 is provided for aiding in housing the spring 42. The gripping member 40 operates in the same manner as the gripping members 6. The gripping member 40 has an extension 47 for housing the spring 43 in its working position. This spring 43 takes the place of spring 19 and is provided with a hook to anchor the spring 21 by catching in the elongated hole 53. A slot 49 is provided for the operation of the spring 43. The gripping member 40 is provided with a loop 48 for finger control. This loop 48 is formed by the lips 44. The bearing member 41 is provided with a guide 54 for the gripping member 40.

Figs. 22 to 26 inclusive show variations in the means for operating the gripping members. There is no change in the gripping members 6. The devices for actuating the gripping members are shown above the sash. These operating devices may be located on the bottom of the sash. Extension bars 57 are pivotally connected to the gripping members 6 and are provided with two elongated lugs 57 and which can be manipulated by one hand of the operator. Extension bars 56 are provided with guides 58 and 59. A spring 60 is threaded in behind the extension bars 56 and in front of the guide 58. Clips 61 pivotally connect the extension bars 56 to the gripping members 6. The blank of Fig. 26 shows the metal members 62 which form the lugs or handles 57.

What I claim, is, a 1. Friction grip sash control comprising in combination with a sash frame and a window frame beveled bearing stops attached to said window frame, gripping bars provided with beveled bearing members adapted to engage the beveled surfaces of said stops, resilient means for pressing said gripping bars in between said stops and said sash frame, and mean for hingedly and adjustably connecting said gripping bars to said sash frame consisting of springs countersunk in the sides of said sash frame and attached thereto and provided with bearings and lugs rigid with saidgripping bars and projected into said bearings. a a

2. Friction grip sash control comprising in combination with a sash frame and a window frame beveled bearing stops attached to said window frame, gripping bars provided with beveled bearing members adapted to engage the beveled surfaces of said stops, resilient means for pressing said gripping bars between said stops and said sash frame, means including interlocking elements for hingedly and adj ustably connecting said gripping bars to said sash frame, and shift keys operatively connected with said beveled stops for shifting said bearing members.

In testimony whereof, I set my hand, this 19th day ofJuly, 1928.

GEORGE E. SRACK.
